Genome sequencing data gives important clues on cancer

Genome sequencing data once regarded as junk is now being used to gain important clues to help understand disease.

New method allows controlled release of drugs; could help develop targeted treatments

Researchers have discovered a method that allows for the controlled release of an active agent on the basis of a magnetic nanovehicle.

Findings could help explain prevalence of urinary tract infections in post-menopausal women

Researchers from Washington University School of Medicine, St. Louis, show that reservoirs of uropathogenic E. coli within the bladder exist in higher numbers post-menopause than pre-menopause in a mouse model, a finding that could help explain the greater prevalence of urinary tract infections in post-menopausal women.

Study shows promising results for cancer treatment

The plasma membrane transporter SLC5A8 can inhibit the spread of tumours by decreasing the amount of the anti-apoptotic protein surviving in tumour cells.

Mice exposed to BPA exhibit spontaneous activity, have leaner body mass

Female mice exposed to Bisphenol A through their mother's diet during gestation and lactation were found to be hyperactive, exhibit spontaneous activity and had leaner body mass than those not exposed to the chemical, researchers at the University of Michigan School of Public Health have discovered.

Early-life exposure to TBT chemical can cause obesity

Exposing pregnant mice to low doses of the chemical tributyltin (TBT) - which was used in marine antifouling paints and is used as an antifungal agent in some paints, certain plastics and a variety of consumer products - can lead to obesity for multiple generations without subsequent exposure, a UC Irvine study has found.

Research shows brain cells regulate blood vessel development

Zhen Huang freely admits he was not interested in blood vessels four years ago when he was studying brain development in a fetal mouse. Instead, he wanted to see how changing a particular gene in brain cells called glia would affect the growth of neurons.

Scientists use magnetic levitation to make in vitro lung tissue more realistic

In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists from Rice University and the Rice spinoff company Nano3D Biosciences have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory.

Researchers initiate first gene therapy clinical trial for Fabry disease

Researchers in Calgary have launched the first gene therapy clinical trial in the world for Fabry disease, a rare inherited enzyme deficiency that can shorten the lifespan of people who have it by as much as 40 years.

Researchers discover safe and efficient way to get large molecules through the cell membrane

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.

Social isolation increases risk of addiction to amphetamine and alcohol

Rats that are socially isolated during a critical period of adolescence are more vulnerable to addiction to amphetamine and alcohol, found researchers at The University of Texas at Austin. Amphetamine addiction is also harder to extinguish in the socially isolated rats.

Research team describes how the brain controls whisker movements in mice

All parents know the infant milestones: turning over, learning to crawl, standing, and taking that first unassisted step. Achieving each accomplishment presumably requires the formation of new connections among subsets of the billions of nerve cells in the infant's brain. But how, when and where those connections form has been a mystery.

Researchers discover unique hairpin-like structure that facilitates Abeta clumping

Alzheimer's disease is the most common cause of late-life dementia. The disorder is thought to be caused by a protein known as the amyloid-beta protein, or Abeta, which clumps together in the brain, forming plaques that are thought to destroy neurons. This destruction starts early, too, and can presage clinical signs of the disease by up to 20 years.

Biomedical engineers identify natural switch that controls breast cancer metastasis

With a desire to inhibit metastasis, Cornell biomedical engineers have found the natural switch between the body's inflammatory response and how malignant breast cancer cells use the bloodstream to spread.

Boosting estrogen levels may help reduce urinary infections in menopausal women

Estrogen levels drop dramatically in menopause, a time when the risk of urinary tract infections increases significantly.

UTHealth NRC to sponsor forum on sports-related concussions

Super Bowl-winning lineman turned orthopaedic surgeon Mark Adickes, M.D., is moderating a free public forum to help parents, athletes and trainers spot the warning signs of concussion.

Study examines associations between blood calcium and ovarian cancer

A new study from Wake Forest Baptist Medical Center is the first to report that high blood calcium levels might predict ovarian cancer, the most fatal of the gynecologic cancers.

Normalizing p62 protein levels in immune system cells could reduce infection in CF patients

New research suggests that lowering excessive levels of a protein in immune system cells could be a strategy to clear an infection that is deadly to patients with cystic fibrosis (CF).

Mice with reduced caloric intake accumulate longer telomeres

One of the indicators of a cell's health is the state of its DNA and containers-the chromosomes-so when these fuse together or suffer anomalies, they can become the source of illnesses like cancer and/or ageing processes.

Hyperbaric treatment restores neurological function in damaged brains

Stroke, traumatic injury, and metabolic disorder are major causes of brain damage and permanent disabilities, including motor dysfunction, psychological disorders, memory loss, and more. Current therapy and rehab programs aim to help patients heal, but they often have limited success.
